Day / August 2, 2017

Today is the anniversary of a letter that changed history. The letter, dated August 2, 1939, was written by physicists Albert Einstein and Leo Szilard; it was addressed to the President of the United States Franklin Delano Roosevelt. The letter’s content warned the president of the Nazi’s possible use of uranium for the development of atomic weapons.

The story behind this historic letter that led to the Manhattan Project, begins in Germany, which prior to 1933 was a hotbed of scientific inquiry: Germany had been awarded 99 Nobel Prizes in science compared to the United States’ 6 Nobel Prizes. The rise of anti-semitism and of Adolf Hitler, however, caused many Jewish scientists to flee Germany.

One of those who fled was physicist Leo Szilard who relocated to England. While sitting at a London traffic light in 1933 he had an epiphany: theoretically the atom could be split, creating a chain reaction of enormous power.

Szilard’s idea moved from theory to fact in 1939 when German scientists successfully split an atom. The fact that German scientists now had the knowledge of the potentially destructive power of the atom in their hands alarmed Szilard.

Traditionally scientists around the world published their breakthroughs for all to see. Szilard was afraid that the German scientists were using this information to develop a bomb. His fears were heightened when Germany invaded Czechoslovakia in 1939 and stopped all exports of uranium ore from the occupied country.

He urged scientists outside of Germany to delay publication of their findings in fission-related areas, and he initiated a meeting with his former teacher Albert Einstein.

Einstein, like Szilard, was a Jew and had fled Germany during the rise of Hitler. By 1939 Einstein’s theory of relativity had made him an international celebrity — just the kind of name recognition that Szilard needed to get his alarm bell heard by world leaders.

Szilard met with Einstein in New York on July 30. Einstein dictated the letter to Szilard in German, and Szilard later translated it into a typed final draft for Einstein’s signature.

The letter’s opening read as follows:

Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of the situation which has arisen seem to call for watchfulness and if necessary, quick action on the part of the Administration. I believe therefore that it is my duty to bring to your attention the following facts and recommendations. (2)

Even Einstein’s signature, however, did not guarantee that the letter would get the attention it deserved. Einstein and Szilard entrusted the letter to Alexander Sachs, an unofficial advisor to F.D.R., but Roosevelt was preoccupied with the growing war in Europe, and Sachs was unable to get an appointment with him until October 1939.

To persuade Roosevelt, Sachs used a historical analogy. He told Roosevelt about an American inventor who met with the French emperor during the Napoleonic Wars. The inventor offered to build a fleet of steamships that could invade England regardless of the weather. Napoleon was incredulous, unable to think beyond ships with sails. He sent the American away. The shortsightedness, arrogance, and lack of imagination of Napoleon saved England and sealed Napoleon’s fate. It was a powerful analogy, and despite the fact that it took time for the Manhattan Project to get off the ground, it was the letter and Sach’s persuasiveness that led to the development of the atomic bomb that Harry Truman had dropped on Hiroshima on August 6, 1945.

Ironically, near the end of the war the Allies discovered that the Germans were at least two years away from developing the bomb. Furthermore, both Szilard and Einstein objected to the United States’ use of the bomb. Even though Einstein did not work directly on the Manhattan Project, he called his decision to sign the letter to President Roosevelt the “one great mistake in my life” (1).

Today’s Challenge:What are examples of the most urgent issues in today’s world, either at the local, national , or international levels? If you were to select one urgent issue, what would it be, and how would you explain your reasoning behind why the issue is so urgent? Select a single issue and writer an open letter to the president or other official who has power to act. Explain in your letter what the issue is and why it is specifically an urgent issue that should be addressed immediately. The purpose of your letter is to persuade the addressee and the general audience that your issue is in fact an urgent issue that needs to be addressed immediately.
